I guess you're using Spring.
If you use Spring injection via an xml file, you must use inheritance:
<bean id="baseAction" class="com....BaseAction" scope="prototype">
</bean>
<bean id="itemDetails" class="com....ItemDetails" scope="prototype"
depends-on="baseAction">
<property name="itemId" ref="itemId"/>
</bean>
<bean id="saveItem" class="com....SaveItem" scope="prototype"
depends-on="baseAction,itemDetails">
</bean>
Cheers,
